You are going to sleep
Goodnight, goodnight
Drifting to sleep
Sleep tight tonight

Empty your mind
Of what beguiles
Promise now don't think
Of crocodiles

Its quiet time
Let everything go
All your frustrations
And worries lay low

Don't think of things
That will make you fuss
Don't think of a wet

(Whistling to melody)

All of your fusses
And frets have to go
They'll only make you
More restless you know

Try not to wriggle 
Or toss or flex
Don't think of a 
Tyr-an-oh-saur-us Rex

No crocodiles
Hippos should stay
In your memory files

Tyranno-saurus Rex
Must go
Sleep little darling
We love you so
